Transportable Self Contained Cutting Box

ABSTRACT

A heated portable vacuum slurry box for efficiently storing and transporting material including drill cuttings from gas and oil well sites. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The features allow for the slurry box to be meet space restriction requirements at a well site while as well as function within the environmental conditions of winter and summer seasons. Jacketed openings, stack mount systems, and a removable power unit allow for efficient use of the slurry box.

FIELD OF TECHNOLOGY

This disclosure relates generally to technology for roll-off self-contained cutting boxes for heated slurry transport, receiving, and dumping in cold climates with freezing temperatures.

BACKGROUND

Drill cuttings are produced during drilling of oil wells and gas wells. The drill cuttings are carried to the surface by a drilling fluid circulating up from the drill bit. The drill cuttings are separated from the drilling fluid so the recycled drilling fluid may be reused during the drilling process. The separated drill cuttings along with a portion of the drilling fluid and other liquids form a cuttings slurry that is often transported to a vacuum tank for holding until is full. Once the tank is full of the cuttings slurry, the cuttings slurry is transportation to a disposal site.

One problem with conventional transporting drill cuttings in a vacuum tank is that the cuttings slurry may freeze in cold weather environments such as Alaska and Canada making it difficult to unload the cuttings slurry from the vacuum box. To solve this problem one solution is to provide for heat energy to keep the drill cuttings from freezing. One example of a heat solution is illustrated in U.S. Pat. No. 10,933,794 to Peterkin titled “Heated slurry transport system.”

Vacuum tanks must be removed from oil and gas well sites in a timely manner such to not impede the function of the oil or gas well site. Such sites are limited in space and storing many vacuum tanks on the oil or gas well site is not possible with current vacuum tank systems. Further portable vacuum tanks which are too large do not fit the requirements to be efficiently emptied at disposal sites. In the warm summer months, poor road conditions cause excess wear on equipment. Transporting vacuum tanks with heating functions over summer roads during times of the year when the heating functions are unneeded unnecessarily causes wear on such equipment.

SUMMARY

This disclosure is directed toward a self-contained heated portable vacuum slurry box which is configured for efficient transportation. The slurry box is such that it can be placed on a vehicle for transportation or moved at a particular location. An example of a vehicle that can be used with the slurry box is a traditionally understood roll-off truck. With this invention, the portable tank can be loaded or unloaded from a roll-off truck. The tank is such that it can hold vacuum when a vacuum pump is fluidly attached to the tank. The vacuum can cause material such as drilling cuttings to be pulled into the portable tank.

The slurry box comprises a vacuum tank, a structure attached to the tank, a mechanical bay, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The vertical tailgate allows for the slurry box to be unloaded in a compact space which does not allow for a traditional swing door that takes additional lateral room. Multiple slurry boxes may be stacked to conserve room on a well site. To adapt the slurry box for stacking, a stacking mount system and a stacking leg system is attached to the structure.

In summer months, the heating function of the slurry box is not needed. In summer months, roads which were frozen during winter months have thawed and become rough, therefore causing additional wear and tear on equipment being transported thereon. To reduce the amount of wear and tear on the slurry box power unit located in the mechanical bay, the power unit is adapted with quick disconnect connectors and quick disconnect fittings to allow for removal from the mechanical bay during summer months.

In winter months, jacketed openings are used on the slurry box to ensure material contained in the tank does not freeze at openings exposed to cold air during transportation. A thermo relief valve is mounted on the tank to ensure the tank does not become positively pressurized, due to warm material in the interior of the tank heating air, to cause expansion and therefore increased air pressure in the enclosed space of the tank.

Figures Detail

FIG. 1 is a 3D perspective of an exemplary slurry box 101. The slurry box 101 is comprised of a tank 102, a structure 103, and a mechanical bay 106. The slurry box 101 has a front 108 and a rear 109. The tank 102 is attached to the structure 103. Attached to the tank 102 is a manhole 104 which can be opened to allow for a person to enter the tank 102 or to load or unload the tank 102. The tank 102 is such that it can withstand full or partial vacuum pressure. When the tank 102 is placed under a vacuum from an external vacuum pump, material may be drawn into the tank 102. Mounted on the tank 102 is a thermo relief valve 105. Fluidly attached to the tank 102 may be one or more openings for loading and unloading. Each opening may be closed to fluidly seal the tank 102. In this exemplary tank 102, a front pipe flange 107 is shown.

The front pipe flange 107 can be used either for loading or unloading depending on requirements dictated by the worksite at which the slurry box 101 is located. A vacuum pump may be fluidly attached to the front pipe flange 107 or any other pipe flange on the slurry box 101. The extent of the vacuum to be applied within the tank 102 may range all the way from relative atmospheric pressure to a full vacuum depending on the application at a worksite. In the event the front pipe flange 107 is not being utilized at a job site, the front pipe flange 107 may be covered or may be connected to a valve which seals the opening. Any opening on the tank 102, including the front pipe flange 107, may be jacketed with an exterior surface to allow a heat fluid flow to be circulated around an inner surface. For example, the front pipe flange 107 may have a five inch inner surface which material may be loaded or unloaded to the tank 102 and a six inch exterior surface.

At the rear of the slurry box 101 a tailgate 110 can be attached. FIG. 1 is displayed without a tailgate 110 attached. The tailgate 110 is attached to hinges on the slurry box 101 which allow for the tailgate 110 to be mechanically opened vertically. By attaching the tailgate 110 on the slurry box 101 such that it is vertically opened ensures that the slurry box 101 does not need additional lateral space to either side. In many applications the slurry box 101 needs to be unloaded at sites which do not allow for excess lateral space around the slurry box 101. When closed the tailgate 110 is sealed to the tank 102 such that the tank 102 may maintain vacuum pressure.

The structure 103 of the slurry box 101 is attached to the tank 102. A ladder may be attached to the slurry box 101 to allow for access to the manhole 104 at the top of the slurry box 101. The structure 103 allows for the slurry box 101 to be lifted, moved, or transported. At the bottom of the slurry box 101 a rear wheel set 112 is attached to the structure 103 near the rear 109. The rear wheel set 112 is as commonly appreciated for use in roll-off containers. In the exemplary embodiment shown in FIG. 1 an optional front wheel set 113 is shown. The rear wheel set 112 and the optional front wheel set 113 as included in some embodiments comprise a base wheel set.

The slurry box 101 may be stacked vertically when more than one slurry box 101 is used. Many gas or oil well sites have limited space on which equipment can be placed and the ability to stack the slurry box 101 is a valuable function. To enable the stacking function, attached to the structure 103 is at least one stacking leg 111 and at least one stacking mount 114. In the exemplary embodiment shown in FIG. 1 four stacking mounts and four stacking legs are demonstrated. A wheel platform 115 may be attached to the structure 103 to support a wheel set when a slurry box 101 is stacked. In the embodiment shown, a set of rear wheel platforms are demonstrated in a position that would support the rear wheel set 112 when stacked. The slurry box 101 my be lifted using d-rings and chains, a forklift, or any other lifting mechanism. When stacked each respective stacking leg 111 fits into each respective stacking mount 114. The one or more stacking mounts collectively comprise a stacking mount system. The one or more stacking legs comprise a stacking leg system. The stacking leg systems fits together with the stacking mount system.

In the embodiment shown in FIG. 1 the slurry box 101 is shown to be similar to a roll-off container. A roll-off container is a portable container which may be transported on a vehicle. In the figure, the slurry box 101 is shown similar to a cable type roll-off container. A cable roll-off container may be pulled or placed on a vehicle such as a tilt-bed vehicle such as a truck or trailer by a winch. A cable attached to the winch may be attached to a hook point 116 on the structure 103. The slurry box 101 may be then pulled onto the vehicle. In an alternative embodiment the structure 103 may be built to allow for the hook point 116 to be attached near the top of the structure 103 to allow for a hook-loader type vehicle to pull the slurry box 101 onto the vehicle. For the purpose of this disclosure, a roll-off vehicle is considered to be either a tilt-bed vehicle, a truck trailer combination, or a hook-loader type vehicle. A truck trailer combination type vehicle is a vehicle 201 where a truck pulls a trailer, the trailer which is a hook-loader type trailer or a tilt-bed type trailer. In a truck trailer combination the slurry box 101 is pulled onto the trailer section of the truck trailer combination just as a slurry box 101 is pulled onto a tilt-bed vehicle or a hook-loader type vehicle.

The slurry box 101 is sized to fit onto a vehicle. The slurry box 101 may be built in a variety of sizes and shapes to accommodate for different vehicles. An exemplary slurry box 101 may be 2.26 meters (89 inches) wide by 7.37 meters (290 inches) long. A slurry box 101 with such dimensions would be compliant with certain various jurisdictional transportation requirements.

A mechanical bay 106 is located within the slurry box 101. In the mechanical bay 106 certain ancillary equipment is located. A power unit 801 for providing heat energy to fluid within warming tubes and jacketed openings is located in the mechanical bay 106. The power unit may also provide energy to power a hydraulic pump to produce flow and pressure to operate various hydraulic functions. Such hydraulic functions include but are not limited to hydraulicly opening the tailgate 110. The power unit 801 may be a diesel engine with a fuel tank, an electric motor with a battery bank, or any other method as appreciated by one with ordinary skill in the art. The mechanical bay 106 is designed to allow for the power unit 801 to be disconnected and removed when not needed. An exhaust port 118 is positioned to allow for gas and air to circulate out of the mechanical bay 106.

The power unit is adapted to provide heat energy to fluid within warming tubes and jacketed openings. The warming tubes and jacketed openings contain a heating fluid which is provided heat from the power unit by the use of a heat exchanger or other method understood by a person with ordinary skill in the art. The fluid within is circulated through the warming tubes and jacketed openings for the purpose of distributing the heat energy. The fluid being circulated is a heated fluid flow.

The thermo relief valve 105 is such that if the pressure within the tank 102 increases, the pressure can be safely emitted from the tank. The thermo relief valve 105 ensures that the tank 102 does not become under a positive pressure.

The slurry box 101 may be constructed of rigid materials, such as steel or aluminum. The structure 103 materials must be of requisite strength to allow for the slurry box 101 to be lifted, transported, and the tank 102 filed with materials. The tank 102 must be constructed in materials capable of withstanding negative pressure up to a full vacuum.
